ALLIED WORLD ASSURANCE COMPANY HOLDINGS, AG
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Expressed in millions, except share, per share, percentage and ratio information)
1. GENERAL

Allied World Assurance Company Holdings, AG, a Swiss holding company (“Allied World Switzerland”), through its wholly-owned subsidiaries (collectively, the “Company”), is a global provider of a diversified portfolio of property and casualty insurance and reinsurance. References to “$” are to the lawful currency of the United States and to “CHF” are to the lawful currency of Switzerland.

On December 18, 2016, the Company entered into a merger agreement with Fairfax Financial Holdings Limited (“Fairfax”), whereby Fairfax will acquire all of the outstanding ordinary shares of Allied World Switzerland. Under the terms of the merger agreement, Allied World Switzerland shareholders will receive a combination of Fairfax subordinate voting shares and cash having a value equal to $54.00 per Allied World Switzerland share (based on the closing price of Fairfax’s subordinate voting shares on December 16, 2016). The merger agreement has been unanimously approved by both companies’ Boards of Directors. The acquisition is expected to be consummated following the satisfaction of customary closing conditions. The acquisition is anticipated to close in the second quarter of 2017. There can be no assurances that the acquisition will occur.

2. BASIS OF PREPARATION AND CONSOLIDATION

These unaudited condensed consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission (“SEC”(the “SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments that are normal and recurring in nature and necessary for a fair presentation of financial position and results of operations as of the end of and for the periods presented. The results of operations for any interim period are not necessarily indicative of the results for a full year.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates reflected in the Company’s financial statements, include, but are not limited to:

The premium estimates for certain reinsurance agreements,
Recoverability of deferred acquisition costs,
The reserve for outstanding losses and loss expenses,
Valuation of ceded reinsurance recoverables,
Determination of impairment of goodwill and other intangible assets, and
Valuation of financial instruments.

Intercompany accounts and transactions have been eliminated on consolidation and all entities meeting consolidation requirements have been included in the unaudited condensed consolidated financial statements.

These unaudited condensed consolidated financial statements, including these notes, should be read in conjunction with the Company’s audited consolidated financial statements, and related notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.2016.
3. NEW ACCOUNTING PRONOUNCEMENTS
In May 2014,February 2016, the Financial Accounting Standards Board (“FASB”(the “FASB”) issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 provides a framework, through a five-step process, for recognizing revenue from customers, improves comparability and consistency of recognizing revenue across entities, industries, jurisdictions and capital markets, and requires enhanced disclosures. Certain contracts with customers are specifically excluded from the scope of ASU 2014-09, including, among others, insurance contracts accounted for under Accounting Standard Codification 944, Financial Services - Insurance. ASU 2014-09 is effective on January 1, 2017 with retrospective adoption required for the comparative periods. With the issuance of ASU 2015-14, this standard will be effective on January 1, 2018 with retrospective adoption required for the comparative periods. The Company is currently assessing the impact the adoption of ASU 2014-09 will have on future financial statements and related disclosures.
In May 2015, the FASB issued Accounting Standards Update 2015-09, “Financial Services - Insurance (Topic 944): Disclosures about Short-Duration Contracts” (“ASU 2015-09”). ASU 2015-09 provides enhanced disclosures, on an annual basis, related to the reserve for losses and loss expenses. The enhanced disclosures required by ASU 2015-09 include (1) net incurred and paid claims development information by accident year, (2) a reconciliation of incurred and paid claims development information to the aggregate carrying amount of the reserve for losses and loss expenses, (3) for each accident

year presented of incurred claims development information, the total of reserves for losses incurred but not reported (IBNR), including expected development on reported claims, included in the reserve for losses and loss expenses and a description of the reserving methodologies and changes to the reserving methodologies, and (4) for each accident year presented of incurred claims development information, quantitative information about claims frequency, as well as a description of methodologies used for determining claim frequency information. ASU 2015-09 is effective for annual periods beginning after December 15, 2015, and as such the disclosures will first be presented in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. The Company is currently assessing the impact the adoption of ASU 2015-09 will have on future disclosures.
In January 2016, the FASB issued Accounting Standards Update 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). ASU 2016-01 changes current U.S. GAAP for public entities by requiring the following, among others: (1) equity securities, except those accounted for under the equity method of accounting, to be measured at fair value with changes in fair value recognized in net income; (2) the use of the exit price when measuring fair value of financial instruments for disclosure purposes; (3) an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value; and (4) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or notes to the financial statements. ASU 2016-01 is effective for annual periods beginning after January 1, 2018, including interim periods. Early application is permitted. The Company is currently assessing the impact the adoption of ASU 2016-01 will have on future financial statements and disclosures.
In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases” (“ASU 2016-02”). ASU 2016-02 changes current U.S. GAAP for lessees to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous U.S. GAAP. ASU 2016-02 is effective for annual periods beginning after January 1, 2019, including interim periods. Early application is permitted. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on future financial statements and disclosures.

Specifically, the Company is still evaluating its existing leases to determine the appropriate classification under the new standard and whether it will adopt the practical expedients allowed under ASU 2016-02.
In June 2016, the FASB issued Accounting Standards Update 2016-09, “Compensation2016-13, “Financial Instruments - Stock CompensationCredit Losses (Topic 718)326): Improvements to Employee Share-Based Payment Accounting”Measurement of Credit Losses on Financial Instruments” (“ASU 2016-09”2016-13”). ASU 2016-092016-13 modifies U.S. GAAP related to the recognition of credit losses by requiringreplacing the following, among others: (1) all excess tax benefits and tax deficiencies are to be recognized as income tax expense or benefit on the income statement (excess tax benefits are recognized regardless of whether the benefit reduces taxes payableincurred loss impairment methodology in the current period); (2) excess tax benefits are to be classified along with other income tax cash flows as an operating activity in the statement of cash flows; (3) in the area of forfeitures, an entity can still follow the current U.S. GAAP practicewith a methodology that reflects expected credit losses and requires consideration of making an entity-wide accounting policy electiona broader range of reasonable and supportable information to estimateinform credit loss estimates. ASU 2016-13 would apply to financial assets such as loans, debt securities, trade receivables, off-balance sheet credit exposures, reinsurance receivables, and other financial assets that have the numbercontractual right to receive cash. The measurement of awardsexpected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The Company's invested assets are expected to vest or may instead account for forfeitures when they occur;measured at fair value through net income, and (4) classificationtherefore those invested assets would not be impacted by the adoption of ASU 2016-13. The Company has other financial assets, such as a financing activity inreinsurance recoverables, that could be impacted by the statementadoption of cash flows of cash paid by an employer to the taxing authorities when directly withholding shares for tax withholding purposes. ASU 2016-092016-13. ASU 2016-13 is effective for annual periods beginning after January 1, 2017,2020, including interim periods. Early application is permitted. The Company is currently assessing the impact the adoption of ASU 2016-092016-13 will have on future financial statements and disclosures. Specifically, the Company is developing a credit impairment methodology for its reinsurance recoverables based on the guidance in ASU 2016-13.
In August 2016, the FASB issued Accounting Standards Update 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 clarifies the classification of receipts and payments in the statement of cash flows. ASU 2016-15 provides guidance related to (1) settlement and payment of zero coupon debt instruments, (2) contingent consideration, (3) proceeds from settlement of insurance claims, (4) proceeds from settlement of corporate and bank-owned life insurance policies, (5) distributions from equity method investees, (6) cash receipts from beneficial interests obtained by a transferor, and (7) general guidelines for cash receipts and payments that have more than one aspect of classification. The only item above that will impact the Company is the guidance related to distributions from equity method investees. The Company currently utilizes the nature of distribution approach for classifying such distributions and will adopt ASU 2016-15 for reporting periods beginning January 1, 2018. As the nature of distribution approach is an acceptable method under ASU 2016-15, the Company does not expect the adoption of ASU 2016-15 to have a material impact on the statement of cash flows.

_______________________

The redemption frequency and notice periods only apply to the investments without redemption restrictions. Some or all of these investments may be subject to a gate as described below.

In general, the Company has invested in hedge funds that require at least 30 days’ notice of redemption and may be redeemed on a monthly, quarterly, semi-annual, annual or longer basis, depending on the fund. Certain hedge funds have lock-up periods ranging from one to three years from initial investment. A lock-up period refers to the initial amount of time an investor is contractually required to invest before having the ability to redeem. Funds that provide for periodic redemptions may, depending on the funds’ governing documents, have the ability to deny or delay a redemption request, called a “gate.” The fund may implement this restriction if the aggregate amount of redemption requests as of a particular date exceeds a specified

fund may implement this restriction because the aggregate amount of redemption requests as of a particular date exceeds a specified level, generally ranging from 15% to 25% of the fund’s net assets. The gate is a method for executing an orderly redemption process to reduce the possibility of adversely affecting investors in the fund. Typically, the imposition of a gate delays a portion of the requested redemption, with the remaining portion settled in cash sometime after the redemption date. Certain funds may impose a redemption fee on early redemptions. Interests in private equity funds cannot be redeemed because the investments include restrictions that do not allow for redemption until termination of the fund.

The following describes each investment type:

Private equity (primary and secondary): Primary equity includesfunds include funds that may invest in companies and general partnership interests, as well as direct investments. Secondary funds buy limited partnership interests from existing limited partners of primary private equity funds. As owners of private equity, funds may seek liquidity by selling their existing interests, plus any remaining commitment, to secondary market participants. These funds cannot be redeemed because the investments include restrictions that do not allow for redemption until termination of the funds.
Levered credit (including mezzanine debt): Levered credit funds invest across the capital structures of upper middle market and middle market companies in connection with leveraged buyouts, mergers and acquisitions, recapitalizations, growth financings, refinancings and other corporate purposes. The most common position in the capital structure of mezzanine funds will be between the senior secured debt holder and the equity; however, the funds in which we are invested may include secured debt, subordinated debt, preferred stock and/or private equity. These funds cannot be redeemed because the investments include restrictions that do not allow for redemption until termination of the funds.
Real estate funds: Private real estate funds invest directly (through debt and equity) in commercial real estate (multifamily, industrial, office, student housing and retail) as well as residential property.  Real estate managers have diversified portfolios that generally follow core, core-plus, value-added or opportunistic strategies.  These funds cannot be redeemed because the investments include restrictions that do not allow for redemption until termination of the funds.
Distressed funds: In distressed debt investing, managers take positions in the debt of companies experiencing significant financial difficulties, including bankruptcy, or in certain positions of the capital structure of structured securities. The manager relies on the fundamental analysis of these securities, including the claims on the assets and the likely return to bondholders. Certain funds cannot be redeemed because the investments include restrictions that do not allow for redemption until termination of the fund.funds.

Equity long/short funds: In equity long/short funds, managers take long positions in companies they deem to be undervalued and short positions in companies they deem to be overvalued. Long/short managers may invest in countries, regions or sectors and vary by their use of leverage and by their targeted net long position.

Unconsolidated Variable Interest Entities

As a result of the adoption of Accounting Standards Update 2015-02, “Amendments to the Consolidation Analysis”, which became effective January 1, 2016, certain limited partnership investments and similar legal entity investments were considered variable interest entities (“VIE's”) as there were no substantive kick-out or other participating rights. These VIE's will not be consolidated because the Company has determined it is not considered the primary beneficiary, as it does not have both the power to direct the activities that most significantly impact the economic performance of the entity and the obligation to absorb losses of the entity that could be potentially significant to the VIE or the right to receive benefits from the entity that could be potentially significant. As such, the Company continues to record its interests in these entities at fair value, with changes in fair value recorded in the consolidated income statements. The Company's interests in these entities are recorded in “other invested assets” in the unaudited condensed consolidated balance sheets (“consolidated balance sheets”). The Company's maximum

Derivative Instruments Not Designated as Hedging Instruments

The Company is exposed to foreign currency risk in its investment portfolio. Accordingly, the fair values of the Company’s investment portfolio are partially influenced by the change in foreign exchange rates. These foreign currency hedging activities have not been designated as specific hedges for financial reporting purposes.

The Company’s insurance and reinsurance subsidiaries and branches operate in various foreign countries and consequently the Company’s underwriting portfolio is exposed to foreign currency risk. The Company manages foreign currency risk by seeking to match liabilities under the insurance policies and reinsurance contracts that it writes and that are payable in foreign currencies with cash and investments that are denominated in such currencies. When necessary, the Company may also use derivatives to economically hedge un-matchedunmatched foreign currency exposures, specifically forward contracts and currency options.

The Company also purchases and sells interest rate future and interest rate swap contracts to actively manage the duration and yield curve positioning of its fixed income portfolio. Interest rate futures and interest rate swaps can efficiently increase or decrease the overall duration of the portfolio. Additionally, interest rate futuresfuture and interest rate swapsswap contracts can be utilized to obtain the desired position along the yield curve in order to protect against certain future yield curve shapes.

The In addition, the Company also purchases options to actively manage its equity portfolio.

The Company has also entered into insurance and reinsurance contracts that are required to be accounted for as derivatives. This will be the case when the insurance or reinsurance contract provides indemnification to the insured or cedent as a result of a change in a variable versus an identifiable insurable event, such as single-trigger industry loss warranties. The Company considers these insurance and reinsurance contracts to be an extension of its overall insurance operations.

6. FAIR VALUE OF FINANCIAL INSTRUMENTS

In accordance with U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. There is a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon whether the inputs to the valuation of an asset or liability are observable or unobservable in the market at the measurement date, with quoted market prices being the highest level (Level 1) and unobservable inputs being the lowest level (Level 3). A fair value measurement will fall within the level of the hierarchy based on the input that is significant to determining such measurement. The three levels are defined as follows:
 
Level 1: Observable inputs to the valuation methodology that are quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2: Observable inputs to the valuation methodology other than quoted market prices (unadjusted) for identical assets or liabilities in active markets. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets in markets that are not active and inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3: Inputs to the valuation methodology that are unobservable for the asset or liability.

(1) In accordance with U.S. GAAP, other invested assets, excluding other private securities, are measured at fair value using the net asset value per share (or its equivalent) practical expedient and have not been classified in the fair value hierarchy.

“Other invested assets” exclude other private securities that the Company did not measure at fair value, but are accounted for using the equity method of accounting. Derivative assets and derivative liabilities relating to foreign exchange contracts and interest rate swaps are classified within “other assets” or “accounts payable and accrued liabilities” on the consolidated balance sheets.

The following describes the valuation techniques used by the Company to determine the fair value of financial instruments held as of the balance sheet date.

Fair Value of Financial Instruments

U.S. government and government agencies: Comprised primarily of bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation and the Federal National Mortgage Association. The fair values of the Company’s U.S. government securities are based on quoted market prices in active markets and are included in the Level 1 fair value hierarchy. The Company believes the market for U.S. Treasury securities is an actively traded market given the high level of daily trading volume. The fair values of U.S. government agency securities are priced using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency securities are included in the Level 2 fair value hierarchy.

(Expressed in millions, except share, per share, percentage and ratio information)



Non-U.S. government and government agencies: Comprised of fixed income obligations of non-U.S. governmental entities. The fair values of these securities are based on prices obtained from international indices and are included in the Level 2 fair value hierarchy.

13

Table of Contents
ALLIED WORLD ASSURANCE COMPANY HOLDINGS, AG
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Expressed in millions, except share, per share, percentage and ratio information)



States, municipalities and political subdivisions: Comprised of fixed income obligations of U.S. domiciled state and municipality entities. The fair values of these securities are based on prices obtained from the new issue market, and are included in the Level 2 fair value hierarchy.

Corporate debt: Comprised of bonds issued by or loan obligations of corporations that are diversified across a wide range of issuers and industries. The fair valuesvalue of corporate debt that are short-term are priced using spread above the LIBOR yield curve, and the fair valuesvalue of corporate debt that are long-term are priced using the spread above the risk-free yield curve. The spreads are sourced from broker-dealers, trade prices and the new issue market. As the significant inputs used to price corporate debtbonds are observable market inputs, the fair values of corporate debt are included in the Level 2 fair value hierarchy, unless the significant inputs used to price the corporate debt securities are broker-dealer quotes and the Company is not able to determine if those quotes are based on observable market inputs, in which case the fair value is included in the Level 3 hierarchy.

Mortgage-backed: Primarily comprised of residential and commercial mortgages originated by both U.S. government agencies (such as the Federal National Mortgage Association) and non-U.S. government agencies. The fair values of mortgage-backed securities originated by U.S. government agencies and non-U.S. government agencies are based on a pricing model that incorporates prepayment speeds and spreads to determine the appropriate average life of mortgage-backed securities. The spreads are sourced from broker-dealers, trade prices and the new issue market. As the significant inputs used to price the mortgage-backed securities are observable market inputs, the fair values of these securities are included in the Level 2 fair value hierarchy, unless the significant inputs used to price the mortgage-backed securities are broker-dealer quotes and the Company is not able to determine if those quotes are based on observable market inputs, in which case the fair value is included in the Level 3 hierarchy.

Asset-backed: Principally comprised of bonds backed by pools of automobile loan receivables, home equity loans, credit card receivables and collateralized loan obligations originated by a variety of financial institutions. The fair values of asset-backed securities are priced using prepayment speed and spread inputs that are sourced from the new issue market or broker-dealer quotes. As the significant inputs used to price the asset-backed securities are observable market inputs, the fair values of these securities are included in the Level 2 fair value hierarchy, unless the significant inputs used to price the asset-backed securities are broker-dealer quotes and the Company is not able to determine if those quotes are based on observable market inputs, in which case the fair value is included in the Level 3 hierarchy.

Equity securities: Comprised of U.S. and foreign common and preferred stocks and mutual funds. Equities are generally included in the Level 1 fair value hierarchy as prices are obtained from market exchanges in active markets. Non-U.S. mutual funds where the net asset value (“NAV”) is not provided on a daily basis are included in the Level 3 fair value hierarchy. Also, the Company's remaining equity interest in an equity security that it no longer accounts for under the equity method of accounting is included in the Level 3 fair value hierarchy as the fair value is based on the enterprise value of that security that is not a publicly traded company.

Other invested assets: Comprised of funds invested in a range of diversified strategies. In accordance with U.S. GAAP, the fair values of the funds are based on the NAV of the funds as reported by the fund manager. The Company does not measure its investments that are accounted for using the equity method of accounting at fair value, unless an other-than-temporary impairment is recorded.

Derivative instruments: The fair value of foreign exchange contracts, and interest rate futures and swaps are priced from quoted market prices for similar exchange-traded derivatives and pricing valuation models that utilize independent market data inputs. The fair value of derivativesforeign exchange contracts, interest rate futures and swaps are included in the Level 2 fair value hierarchy. The fair value of the insurance and reinsurance contracts are based on an internal model that estimates the expected value based on multiple scenarios (i.e., Monte-Carlo simulation) and discounted back to current value. The key unobservable inputs are the discount rate, which was 10%, and the values of the underlying insured risks. Given the inputs to the internal model are unobservable, the fair value of the insurance and reinsurance contracts are included in the Level 3 fair value hierarchy.

(Expressed in millions, except share, per share, percentage and ratio information)



Senior notes: The fair value of the senior notes is based on reported trades. The fair value of the senior notes is included in the Level 2 fair value hierarchy.

Other long-term debt: Comprised of the mortgage and credit facility associated with the purchase of office space in Switzerland. The fair value of the other long-term debt is based on the value of the debt using current interest rates. The fair value of the other long-term debt is included in the Level 2 fair value hierarchy.

Non-recurring Fair Value of Financial Instruments

The Company measures the fair value of certain assets on a non-recurring basis, generally quarterly, annually, or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include investments accounted for using the equity method, goodwill and intangible assets. The Company uses a variety of techniques to measure the fair value of these assets when appropriate, such as discounted expected future cash flows or market multiple models.

(Expressed in millions, except share, per share, percentage and ratio information)

described below:

Investments accounted for using the equity method: When the Company determines that the carrying value of these assets may not be recoverable, the Company records the assets at fair value with the loss recognized in income. In such cases, the Company measures the fair value of these assets using the techniques discussed above.

Goodwill and intangible assets: The Company tests goodwill and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, but at least annually for goodwill and indefinite-lived intangibles. When the Company determines that goodwill and indefinite-lived intangible assets may be impaired, the Company uses various techniques, including discounted expected future cash flows and market multiple models, to measure fair value.

Transfers out of Level 3 are primarily attributable to the availability of market observable information.

The Company attempts to verify the significant inputs used by broker-dealers in determining the fair value of the securities priced by them. If the Company could not obtain sufficient information to determine if the broker-dealers were using

(Expressed in millions, except share, per share, percentage and ratio information)


significant observable inputs, then such securities have been transferred to the Level 3 fair value hierarchy. The Company believes the prices obtained from the broker-dealers are the best estimate of fair value of the securities being priced, as the broker-dealers are typically involved in the initial pricing of the security, and the Company has compared the price per the broker-dealer to other pricing sources and noted no material differences. The Company recognizes transfers between levels at the end of the reporting period. There were no transfers between Level 1 and Level 2 during the period.

The Company’s external investment accounting service provider receives prices from internationally recognized independent pricing services to measure the fair values of its fixed maturity investments. Pricing sources are evaluated and selected in a manner to ensure that the most reliable sources are used. The Company uses a pricing service ranking to consistently select the most appropriate pricing service in instances where it receives multiple quotes on the same security. The Company obtains multiple quotes for the majority of its securities. The independent pricing sources obtain market quotations and actual transaction prices for securities that have quoted prices in active markets. Each pricing service has its own

proprietary method for determining the fair value of securities that are not actively traded. In general, these methods involve the use of “matrix pricing” in which the independent pricing service uses observable market inputs, including, but not limited to, reported trades, benchmark yields, broker-dealer quotes, interest rates, prepayment speeds, default rates and such other inputs as are available from market sources to determine a reasonable fair value.

All of the Company’s fixed maturity investment securities classified as Level 3 are valued based on unadjusted broker-dealer quotes. This includes less liquid securities such as lower quality asset-backed securities, commercial mortgage-backed securities and residential mortgage-backed securities. The primary valuation inputs include monthly payment information, the probability of default, loss severity rates and estimated prepayment rates. Significant changes in these inputs in isolation would result in a significantly lower or higher fair value measurement. In general, a change in the assumption of the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity in an event of default and prepayment rates.

The Company records the unadjusted price provided and validates this price through a process that includes, but is not limited to, monthly and/or quarterly: (i) comparison of prices between two independent sources, with significant differences requiring additional price sources; (ii) quantitative analysis (e.g., comparing the quarterly return for each managed portfolio to their target benchmark, with significant differences identified and investigated); (iii) evaluation of methodologies used by external parties to calculate fair value, including a review of the inputs used for pricing; (iv) comparing the price to the Company’s knowledge of the current investment market; and (v) back-testing, which includes randomly selecting purchased or sold securities and comparing the executed prices to the fair value estimates from the pricing service. In addition to internal controls, management relies on the effectiveness of the valuation controls in place at the Company’s external investment accounting service provider (supported by a Statement on Standards for Attestation Engagements No. 16 report) in conjunction with regular discussion and analysis of the investment portfolio’s structure and performance.

For the three months ended March 31, 2017, the Company recorded net favorable prior year reserve development primarily due to lower than expected claims development in the Global Markets Insurance and Reinsurance segments, partially offset by unfavorable prior year reserve development in the North American Insurance segment. The unfavorable loss reserve development in the North American Insurance segment was primarily due to higher than expected reported losses in the casualty line of business for the 2012 and 2014 loss years, the professional liability line of business for the 2013 loss year, the property line of business for the 2015 and 2016 loss years, the healthcare line of business for the 2012 and 2013 loss years and the other specialty line of business for the 2013 and 2015 loss years.

For the three months ended March 31, 2016, the Company recorded net favorable prior year reserve development in each of its operating segments primarily due to actual loss emergence being lower than initially expected. The net favorable prior year reserve development in the North American Insurance segment was primarily related to the professional liability and programs lines of business, partially offset by net unfavorable prior year reserve development in the casualty line of business. The net favorable reserve development in the Global Markets Insurance segment was primarily related to the other specialty line of business partially offset by unfavorable reserve development in the professional liability and casualty lines of business. The net favorable prior year reserve development in the Reinsurance segment was primarily related to the property reinsurance and specialty reinsurance lines of business, partially offset by net unfavorable prior year reserve development in the casualty reinsurance line of business.

For the three months ended March 31, 2015, the Company recorded net favorable prior year reserve development in each of its operating segments due to actual loss emergence being lower than initially expected. The net favorable prior year reserve development in the North American Insurance segment was primarily related to the professional liability and general casualty lines of business, partially offset by net unfavorable prior year reserve development in the healthcare line of business. The Global Markets Insurance segment had favorable prior year reserve development across most major lines of business. The net favorable prior year reserve development in the Reinsurance segment was primarily related to the property reinsurance and casualty reinsurance lines of business partially offset by unfavorable reserve development in the specialty line of business.

WhileAlthough the Company has experienced favorable reserve development in its insurance and reinsurance lines, there is no assurance that conditions and trends that have affected the development of liabilities in the past will continue. It is not appropriate to extrapolate future redundancies based on prior years’ development. The methodology of estimating loss reserves is periodically reviewed to ensure that the key assumptions used in the actuarial models continue to be appropriate.

8. INCOME TAXES

Restricted stock units (“RSUs”) vest pro-rata over four yearsFor the three months ended March 31, 2017 and 2016, a weighted average of nil and 353,679 RSUs, respectively, were considered anti-dilutive and were therefore excluded from the datecalculation of grant. The compensation expense for the RSUs is based on the fair market value of Allied World Switzerland’s common shares at the date of grant. The Company estimates the expected forfeitures of RSUs at the date of grant and recognizes compensation expense only for those awards that the Company expects to vest. The forfeiture assumption is ultimately adjusted to the actual forfeiture rate.

Performance-based equity awards represent the right to receive a number of common shares in the future, based upon the achievement of established performance criteria during an applicable performance period. Based on the performance goals, the performance-based equity awards granted in 2016, 2015 and 2014 are expensed at 100%, 100% and 75%, respectively, of the fair value of Allied World Switzerland's common shares on the date of grant. The expense is recognized over the performance period.diluted earnings per share.

b) Cash-equivalent stock awards

As part of the Company’s annual year-end compensation awards, the Company granted both awards classified as equity and cash-equivalent stock awards. The cash-equivalent awards were granted to employees who received RSUs and performance-based equity awards in tandem with stock-based awards. The cash-equivalent RSU awards vest pro-rata over four years from the date of grant. The cash-equivalent performance-based equity awards vest after a three-year performance period. The amount payable per unit awarded will be equal to the price per share of Allied World Switzerland’s common shares, and as such the Company measures the value of an award each reporting period based on the period-ending share price. The effects of changes in the share price at each period-end during the service period are recognized as changes in compensation expense ratably over the service period. The liability is included in “accounts payable and accrued liabilities” in the consolidated balance sheets and changes in the liability are recorded in “general and administrative expenses” in the consolidated income statements.

12. SEGMENT INFORMATION

The determination of reportable segments is based on how the Company's chief operating decision maker, the Chief Executive Officer,senior management monitors the Company’s underwriting operations. Management monitors the performance of its direct underwriting operations based on the geographic location of the Company’s offices, the markets and customers served and the type of accounts written. The Company is currently organized into three operating segments: North American Insurance, Global Markets Insurance and Reinsurance. All product lines of business fall within these classifications.

The North American Insurance segment includes the Company’s specialty insurance operations in the United States, Bermuda and Canada, as well as the Company's claimclaims administration services operation. This segment provides both property and specialty casualty insurance primarily to North American domiciled accounts. The Global Markets Insurance segment includes the

(Expressed in millions, except share, per share, percentage and ratio information)


Company’s specialty insurance operations in Europe and Asia Pacific, which includes offices in Australia,Dublin, Hong Kong, Labuan, London, Singapore, Sydney, and Singapore.Zug, as well as the Company's insurance agency operation. This segment provides both property and casualty insurance primarily to non-North American domiciled accounts. The Reinsurance segment includes the Company’s reinsurance operations in Bermuda, Labuan, London, Miami, New York, Singapore, the United States and Zug. This segment provides reinsurance of property, general casualty, professional liability, specialty lines and property catastrophe coverages written by insurance companies. The Company presently writes reinsurance on both a treaty and a facultative basis, targeting several niche reinsurance markets.

Responsibility and accountability for the results of underwriting operations are assigned by major line of business within each segment. Because the Company does not manage its assets by segment, investment income, interest expense and total assets are not allocated to individual reportable segments. General and administrative expenses are allocated to segments based on various factors, including expenses directly attributable to individual segments, staff count and each segment’s proportional share of gross premiums written.

The Company measures its segment profit or loss as underwriting income or loss plus other insurance-related income and expenses, which may include the net earnings from our claims administration services operations and other income or expense that is not directly related to our underwriting operations. Management measures results for each segment's underwriting income or loss on the basis of the “loss and loss expense ratio,” “acquisition cost ratio,” “general and administrative expense ratio,” “expense ratio” and the “combined ratio.” The “loss and loss expense ratio” is derived by dividing net losses and loss expenses by net premiums earned. The “acquisition cost ratio” is derived by dividing acquisition costs by net premiums earned. The “general and administrative expense ratio” is derived by dividing general and administrative expenses by net premiums earned. The expense ratio is the sum of the “acquisition cost ratio” and the “general and administrative expense ratio”. The “combined ratio” is the sum of the “loss and loss expense ratio,” the “acquisition cost ratio” and the “general and administrative expense ratio.”

Note on Forward-Looking Statement

This Form 10-Q and other publicly available documents may include, and our officers and representatives may from time to time make, projections concerning financial information and statements concerning future economic performance and events, plans and objectives relating to management, operations, products and services, and assumptions underlying these projections and statements. These projections and statements are forward-looking statements within the meaning of The Private Securities Litigation Reform Act of 1995 and are not historical facts but instead represent only our belief regarding future events, many of which, by their nature, are inherently uncertain and outside our control. These projections and statements may address, among other things, our strategy for growth, product development, financial results and reserves. Actual results and financial condition may differ, possibly materially, from these projections and statements and therefore you should not place undue reliance on them. Factors that could cause our actual results to differ, possibly materially, from those in the specific projections and statements are discussed throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations and in “Risk Factors” in Item 1A. of Part I of our 20152016 Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”)SEC on February 22, 201628, 2017 (the “2015“2016 Form 10-K”). We are under no obligation (and expressly disclaim any such obligation) to update or revise any forward-looking statement that may be made from time to time, whether as a result of new information, future developments or otherwise.

Overview

Our Business

We are a Swiss-based global provider of a diversified portfolio of property and casualty insurance and reinsurance products with operations in Australia, Bermuda, Canada, Europe, Hong Kong, Labuan, Singapore and the United States as well as our Lloyd’s Syndicate 2232. We manage our business through three operating segments: North American Insurance, Global Markets Insurance and Reinsurance. As of March 31, 2016,2017, we had approximately $13.7$13.4 billion of total assets, $3.5$3.6 billion of total shareholders’ equity and $4.9$4.5 billion of total capital, which includes shareholders’ equity, senior notes and other long-term debt. Total capital includes our $500 million senior notes that we issued in October 2015, the proceeds of which we intend to use to refinance our $500 million senior notes due to mature in August 2016.

During the three months ended March 31, 2016,2017, the property and casualty insurance and reinsurance industry continuedstarted to experience challengingsee improvement in pricing and market conditions due to continued heavy competition and the continued low investment return environment. Despite these market conditions, we selectively expanded our operations but also did not renew business or write new accounts that did not meet our underwriting standards. For the quarter, we now included our first full year of results from the Hong Kong and Singapore operations acquired from RSA, which drove the growth in our Global Markets Insurance segment. Our North American Insurance segment experienced an overall rate reduction in the current period driven largely by rate decreases in our property lineselect lines of business. For ourOur Reinsurance segment we continued to experience unfavorable market conditions in terms of pricing, and terms and conditions, and either did not renew or decreased line sizes on certain treaties in response to these market conditions. As a result, our

Our consolidated gross premiums written decreased by $17.1$2.6 million, or 1.9%0.3%, for the three months ended March 31, 20162017 compared to the three months ended March 31, 2015.2016. The decrease was mainly driven by lower gross premiums written in our Reinsurance segment partially offset by growth in our North American Insurance segment. Overall, our combined ratio is higher by 7.93.1 percentage points, driven primarily by lower net favorable prior year reserve development.development and higher general and administrative expenses.

Our net income decreasedincreased by $50.3$6.2 million to $74.1$80.3 million compared toduring the three months ended March 31, 2015.2017 compared to $74.1 million for the three months ended March 31, 2016. The decreaseincrease was primarily due to thehigher net realized gains on our investments of $21.8 million and lower interest expense of $9.6 million, partially offset by lower underwriting income reported by each of our operating segments and lower total investment return.$18.4 million.

Non-GAAP Financial Measures

In presenting the Company’s results, management has included and discussed certain non-GAAP financial measures, as such term is defined in Item 10(e) of Regulation S-K promulgated by the SEC. Management believes that these non-GAAP measures, which may be defined differently by other companies, better explain the Company’s results of operations in a manner that allows for a more complete understanding of the underlying trends in the Company’s business. However, these measures should not be viewed as a substitute for those determined in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Operating income and operating income per share

Operating income is an internal performance measure used in the management of our operations and represents after-tax operational results excluding, as applicable, net realized investment gains or losses, net foreign exchange gain or loss, and other non-recurring items. We exclude net realized investment gains or losses, net foreign exchange gain or loss and any other non-recurring items from our calculation of operating income because these amounts are heavily influenced by and fluctuate in part according to the availability of market opportunities and other factors. In addition to presenting net income determined in accordance with U.S. GAAP, we believe that showing operating income enables investors, analysts, rating agencies and other users of our financial information to more easily analyze our results of operations and our underlying business performance. Operating income should not be viewed as a substitute for U.S. GAAP net income.








The following is a reconciliation of operating income to its most closely related U.S. GAAP measure, net income.

Diluted




















Tangible shareholders' equity and diluted book value per share

We have included tangible shareholders' equity, which is total shareholders' equity excluding goodwill and intangible assets, because it represents a more liquid measure of the Company's net assets than total shareholders' equity. We have also included diluted book value per share because it takes into account the effect of dilutive securities; therefore, we believe it is an important measure of calculating shareholder returns.return.

Relevant Factors

Revenues

We derive our revenues primarily from premiums on our insurance policies and reinsurance contracts, net of any reinsurance or retrocessional coverage purchased. Insurance and reinsurance premiums are a function of the amounts and types of policies and contracts we write, as well as prevailing market prices. Our prices are determined before our ultimate costs, which may extend far into the future, are known. In addition, our revenues include income generated from our investment

portfolio, consisting of net investment income and net realized investment gains or losses, and other income related to our non-insurance operations. Investment income is principally derived from interest and dividends earned on investments, as well as distributed and undistributed income from equity method investments, partially offset by investment management expenses and fees paid to our custodian bank. Net realized investment gains or losses include gains or losses from the sale of investments, as well as the change in the fair value of investments that we mark-to-market through net income. Other income currently includes revenue from our third-party claims administration services.services, insurance agency operation, changes in fair value related to insurance and reinsurance contracts accounted for as derivatives, and other non-recurring income.

Expenses

Our expenses consist largely of net losses and loss expenses, acquisition costs and general and administrative expenses. Net losses and loss expenses incurred are comprised of three main components:

losses paid, which are actual cash payments to insureds and reinsureds, net of recoveries from reinsurers;
outstanding loss or case reserves, which represent management’s best estimate of the likely settlement amount for known claims, less the portion that can be recovered from reinsurers; and

reserves for losses incurred but not reported, or “IBNR”, which are reserves (in addition to case reserves) established by us that we believe are needed for the future settlement of claims. The portion recoverable from reinsurers is deducted from the gross estimated loss.

Acquisition costs are comprised of commissions, brokerage fees, insurance taxes and other acquisition-related costs such as profit commissions and amortization of insurance-related intangible assets, and are reduced for ceding commission income received on our ceded reinsurance. Commissions and brokerage fees are usually calculated as a percentage of premiums and depend on the market and line of business. Acquisition costs are reported after (1) deducting commissions received on ceded reinsurance, (2) deducting the part of deferred acquisition costs relating to the successful acquisition of new and renewal insurance and reinsurance contracts and (3) including the amortization of previously deferred acquisition costs.

General and administrative expenses include personnel expenses including stock-based compensation expense, rent expense, professional fees, information technology costs and other general operating expenses.

Ratios

We measure segment profitincome or loss as underwriting income or loss plus other insurance-related income and expenses, which may include the net earnings from our third-party claims administration services operation, insurance agency operation, changes in fair value for insurance and reinsurance contracts accounted for as derivatives, and other income or expense that is not directly related to our underwriting operations. We also measure the results for each segmentsegment's underwriting income or loss on the basis of the “loss and loss expense ratio,” “acquisition cost ratio,” “general and administrative expense ratio,” “expense ratio” and the “combined ratio.” Because we do not manage our assets by segment, investment income, interest expense and total assets are not allocated to individual reportable segments. General and administrative expenses are allocated to segments based on various factors, including expenses directly attributable to individual segments, staff count and each segment’s proportional share of gross premiums written. The loss and loss expense ratio is derived by dividing net losses and loss expenses by net premiums earned. The acquisition cost ratio is derived by dividing acquisition costs by net premiums earned. The general and administrative expense ratio is derived by dividing general and administrative expenses by net premiums earned. The expense ratio is the sum of the acquisition cost ratio and the general and administrative expense ratio. The combined ratio is the sum of the loss and loss expense ratio, the acquisition cost ratio and the general and administrative expense ratio.

Critical Accounting Policies
It is important to understand our accounting policies in order to understand our financial position and results of operations. Our unaudited condensed consolidated financial statements reflect determinations that are inherently subjective in nature and require management to make assumptions and best estimates to determine the reported values. If events or other factors cause actual results to differ materially from management’s underlying assumptions or estimates, there could be a material adverse effect on our financial condition or results of operations. We believe that some of the more critical judgments in the areas of accounting estimates and assumptions that affect our financial condition and results of operations are related to reserves for losses and loss expenses, reinsurance recoverables, premiums and acquisition costs, valuation of financial instruments and goodwill and other intangible asset impairment valuation. For a detailed discussion of our critical accounting policies, please refer to our 20152016 Annual Report on Form 10-K. There were no material changes in the application of our critical accounting estimates subsequent to that report.

Corporate income tax expense or benefit is generated through our operations in Australia, Canada, Europe, Hong Kong, Labuan, Singapore and the United States. Our income tax expense or benefit may fluctuate significantly from period to period depending on the geographic distribution of pre-tax net income or loss in any given period between different jurisdictions with different tax rates. The geographic distribution of pre-tax net income or loss can vary significantly between periods principally due to the geographic location of the business written, the mix of business and the profitability of such business, the geographic location of investment income, the geographic location of net losses and loss expenses incurred, and the amount of inter-company reinsurance utilized for rating agency purposes.

IncomeWe recorded an income tax expensebenefit of $2.5 million for the three months ended March 31, 2016 decreased by $5.82017 compared to an income tax expense of $1.1 million compared tofor the three months ended March 31, 2015.2016. The decrease in income tax expensebenefit recognized in the current year was primarily due to lower taxablean income intax benefit recorded for our U.S. operations.operations as well as recording an income tax benefit of $1.8 million related to excess tax benefits due to the adoption of Accounting Standards Update 2016-09 (“ASU 2016-09”).

Premiums. Gross premiums written decreasedincreased by $1.6$17.6 million, or 0.4%4.6%, for the three months ended March 31, 20162017 compared to the same period in 2015.2016. The decreaseincrease in gross premiums written was primarily due to the result of lower premiumsgrowth in our casualtyprograms line of business due to lower non-recurring premiums in the current period compared to the prior period. These

reductions were partially offset byfrom existing programs and new business, in particularprograms added since March 31, 2016. We also had growth in our other specialty lines of business, such as environmental and increased premiums from our programs line of business,construction, driven primarily by new business. This was partially offset by the growthnon-renewal of healthcare business that did not meet our underwriting requirements, and lower transactional-based premiums related to mergers and acquisitions in existing programs.our professional liability line of business.

The reduction in reported large property losses decreased the loss and loss expense ratio by 3.8 percentage points.2016.

The unfavorable development in our other specialty line of business was primarily related to several large claims reported in the current period. We also recorded favorable development across all lines of business for the 2011 and prior loss years due to actual loss development being lower than expected. The unfavorable development in our casualty line of business for the 2012 and 2014 loss years and our healthcare line of business for the 2012 and 2013 loss years was due to higher than expected reported losses.

Current year non-catastrophe losses and loss expenses

The increasedecrease in the current year non-catastrophe losses and loss expenses, and related ratio, was primarily due to higherlower net losses incurred losses related to the acquired Asian operations, as well as higher reported losses primarily related to our property and aviation lines of business. The increase in reported losses in the current period comparedrelated to our construction workers compensation product within our casualty line of business, the prior period increased the losstrade credit and loss expense ratio by 4.4 percentage points.aviation products within our other specialty line of business, and lower non-catastrophe property losses.

Current year property catastrophe losses and loss expenses

During the three months ended March 31, 2017, we incurred net losses of $3.5 million related to Australian Cyclone Debbie. During the three months ended March 31, 2016, and March 31, 2015, we did not have any net losses incurred that we classified as property catastrophe losses.

Comparison of Three Months Ended March 31, 20162017 and 20152016

Premiums. Gross premiums written decreased by $70.5$20.5 million, or 16.0%5.6%, for the three months ended March 31, 20162017 compared to the same period in 20152016. The decrease was primarily due to non-renewalscertain treaties that were written during the three months ended March 31, 2016 that were extended, and therefore not subject to renewal, during the three months ended March 31, 2017. The decrease in gross premiums written was also due to non-renewal of certain treaties across all lines of business, due either to poor terms and conditions or cedents retaining more of their own business, and lower premiums on renewed treaties. As it relates to lower premiums on renewedbusiness. The non-renewal of treaties the main driver for the decrease in property reinsurance gross premiums written was a reduction in our participation on the collateralized property catastrophe reinsurance program through Aeolus Re. These reductions were partially offset by new business written.written for each line of business.

The increase in ceded premiums was the result of a new retrocessional quota share reinsurance treaty for our property reinsurance line of business, and the higher cost of our outward property catastrophe reinsurance coverage in the current period than in the prior period.written.

Net premiums earned decreased by $35.9$12.4 million, or 17.5%7.3%, as a result of the decrease in net premiums written during 20152016 and into 2016, and higher ceded premiums earned for the outward property catastrophe reinsurance coverage in the current period compared to the prior period.2017.

Current year non-catastrophe losses and loss expenses

The decrease in the current year non-catastrophe losses and loss expenses, and the related ratio, was primarily due to the reduction inlower net premiums earned during the three months ended March 31, 2017 compared to the three months ended March 31, 2016, and lower reported largethan expected non-catastrophe property losses in the current period compared to the prior period. The increase in the non-catastrophe losses and loss expense ratio was due to higher loss ratio assumptions partially offset by lower reported large property losses.

Current year property catastrophe losses and loss expenses

During the three months ended March 31, 2017, we incurred net losses of $7.5 million related to Australian Cyclone Debbie. During the three months ended March 31, 2016, and March 31, 2015, we did not have any net losses incurred that we classified as property catastrophe losses.

Prior year losses and loss expenses

Overall, our Reinsurance segment recorded net favorable reserve development of $21.2$12.4 million during the three months ended March 31, 20162017 compared to net favorable reserve development of $23.2$21.2 million for the three months ended March 31, 2015,2016, as shown in the tables below.

The net favorable reserve development in the 2014 loss year was due to favorable reserve development in the property reinsurance line of business due to benign reported loss activity, partially offset by unfavorable development in the specialty reinsurance line of business primarily due to higher than expected reported losses in our crop reinsurance line of business. We also experienced net favorable development in the 2009 and prior loss years in our casualty reinsurance line of business, primarily in our U.S. and Bermuda casualty reinsurance lines, as a result of actual loss emergence being lower than anticipated in the 2008 and 2009 loss years.

The increase in the acquisition cost ratio was primarily due to higher profit commissions inrelated to our crop reinsurance line of business driven by favorable results for the current period than in the prior period, as well as the impact of higher ceded premiums earned from our outward property catastrophe reinsurance coverage which does not have any ceding commission income.period.

We participate in certain lines of business where claims may not be reported for many years. Accordingly, management does not solely rely solely upon reported claims on these lines for estimating ultimate liabilities. We also use statistical and actuarial methods to estimate expected ultimate losses and loss expenses. Loss reserves do not represent an exact calculation of liability. Rather, loss reserves are estimates of what we expect the ultimate resolution and administration of claims will cost. These estimates are based on various factors, including underwriters’ expectations about loss experience, actuarial analysis, comparisons with the results of industry benchmarks and loss experience to date. Loss reserve estimates are refined as experience develops and as claims are reported and resolved. Establishing an appropriate level of loss reserves is an inherently uncertain process. Ultimate losses and loss expenses may differ from our reserves, possibly by material amounts.

For statistical reasons, it is not appropriate to add together the ranges of each business segment in an effort to determine the low and high range around the consolidated loss reserves.

Our range for each business segment was determined by utilizing multiple actuarial loss reserving methods along with various assumptions of reporting patterns and expected loss ratios by loss year. The various outcomes of these techniques were combined to determine a reasonable range of required loss and loss expense reserves. WhileAlthough we believe our approach to determine the range of loss and loss expense is reasonable, there are no assurances that actual loss experience will be within the ranges of loss and loss expense noted above.

Our selection of the actual carried reserves is generally above the midpoint of the range. We believe that we should be prudent in our reserving practices due to the lengthy reporting patterns and relatively large limits of net liability for any one risk of our direct excess casualty business and of our casualty reinsurance business. Thus, due to this uncertainty regarding estimates for reservesreserve for losses and loss expenses, we have carried our consolidated reservesreserve for losses and loss expenses, net of reinsurance recoverable, above the midpoint of the low and high estimates for the consolidated net losses and loss expenses. We believe that relying on the more prudent actuarial indications is appropriate for these lines of business.

We remain obligated for amounts ceded in the event our reinsurers do not meet their obligations. Accordingly, we have evaluated the reinsurers that are providing reinsurance protection to us and will continue to monitor their credit ratings and financial stability. We generally have the right to terminate our treaty reinsurance contracts at any time, upon prior written notice to the reinsurer, under specified circumstances, including the assignment to the reinsurer by A.M. Best of a financial strength rating of less than “A-.” Approximately 99% of ceded reserves as of March 31, 20162017 were recoverable from reinsurers who had an A.M. Best rating of “A” or higher.

Liquidity and Capital Resources

Liquidity

Liquidity is a measure of our ability to access sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. The Company believes that its cash flows from operations and investments will provide sufficient liquidity for the foreseeable future.

Holdings is a holding company and transacts no business of its own. Cash flows to Holdings may comprise dividends, advances and loans from its subsidiary companies. Holdings is therefore reliant on receiving dividends and other permitted distributions from its subsidiaries to make dividend payments on its common shares.

Our operating subsidiaries depend upon cash inflows from premium receipts, net of commissions, investment income and proceeds from sales and redemptions of investments. Cash outflows for our operating subsidiaries are in the form of claims payments, net of reinsurance recoveries, reinsurance premium payments, purchasepurchases of investments, operating expenses and income tax payments as well as dividend payments to the holding company.Holdings.

Historically, our operating subsidiaries have generated sufficient cash flows to meet all of their obligations. Because of the inherent volatility of our business, the seasonality in the timing of payments by insureds and cedents, the irregular timing of loss payments, and the impact of a change in interest rates and credit spreads on the investment income as well as seasonality in coupon payment dates for fixed income securities, cash flows from operating activities may vary between periods. In the unlikely event that paid losses exceed operating cash flows in any given period, we would use our cash balances available, liquidate a portion of our investment portfolio or borrow under our revolving loan facility (see “Credit Facilities” below) in order to meet our short-term liquidity needs.

Our total investments and cash and cash equivalents totaled $9.6$9.0 billion as of March 31, 2016,2017, the main components of which were investment grade fixed income securities and cash and cash equivalents. As of March 31, 2016,2017, we held $772.0$1,284.9 million of unrestricted cash and cash equivalents and $761.1$989.0 million of fixed income securities with a maturity of less than one year to meet short-term liquidity needs. Our remaining fixed income securities, equity securities and “other invested assets” are available to meet our long-term liquidity needs.


As of March 31, 2016,2017, we had $150$200 million available under our revolving loan facility.

Dividend Restrictions

The jurisdictions in which our operating subsidiaries are licensed to write business impose regulations requiring companies to maintain or meet various defined statutory ratios, including solvency and liquidity requirements. Some jurisdictions also place restrictions on the declaration and payment of dividends and other distributions. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” in the Company’s 20152016 Annual Report on Form 10-K.

In connection with the announced transaction with Fairfax, at a special meeting of the Company’s shareholders held on March 22, 2017, the Company’s shareholders approved the payment of a special cash dividend of $5.00 per common share, or approximately $437.0 million based on the common shares outstanding as of March 31, 2017, and agreed to forego the fourth installment of the previously approved $0.26 quarterly dividend.  The special dividend is conditioned upon, and will be payable shortly after, the consummation of the exchange offer contemplated by the Fairfax transaction.

The primary sources of cash inflows from operating activities are premiums received, loss payments from reinsurers, return of funds heldfunds-held balances related to our assumed collaterlizedcollateralized property catastrophe reinsurance program through Aeolus Re Ltd., and investment income. The primary sources of cash outflows from operating activities are ceded premiums paid to reinsurers, claims paid, contributions of funds heldfunds-held balances, commissions paid, operating expenses, interest expense and income taxes. The primary factor in our ability to generate positive operating cash flow is underwriting profitability. We have generated positive operating cash flow for more than 1211 consecutive years.

In our casualty lines of business, claims may be reported and settled many years after the coverage period has terminated. As a result, we expect that we will generate significant operating cash flow as we accumulate casualty loss reserves on our balance sheet. In our property lines of business, claims are generally reported and paid within a relatively short period of time and we expect volatility in our operating cash flows as losses are incurred. We expect increases in the amount of expected loss payments in future periods with a resulting decrease in operating cash flow; however, we do not expect loss payments to exceed the premiums generated. Actual premiums written and collected and losses and loss expenses paid in any period could vary materially from our expectations and could have a significant and adverse effect on operating cash flow.

The increasedecrease in cash flows from operations for the three months ended March 31, 20162017 compared to the three months ended March 31, 20152016 was primarily due to a net reduction inlower cash receipts from our funds held balances related to the assumed collaterlizedcollateralized property catastrophe reinsurance program withthrough Aeolus Re. We lowered our participation inRe Ltd. during the three months ended March 31, 2017 compared to the three months ended March 31, 2016, as well as higher net paid losses and lower net premiums written during the current year program which reduced our fundingperiod compared to the prior period.

Cash flows used in or provided by investing activities consist primarily of proceeds on the sale of investments and payments for investments or businesses acquired in addition to changes in restricted cash. The increase in cash flows used in investing activities to cash flows provided by investing activities was due to higher net sales of investments during the current period as well as receivedcompared to the prior period. This was primarily driven by selling a portion of our U.S. municipal bond portfolio and keeping the proceeds from prior underwriting years.in short-term cash equivalent funds.


Cash flows provided by or used in financing activities consist primarily of capital raising activities, which include the issuance of common shares or debt, the repurchase of our common shares, the payment of dividends and the repayment of debt. The increase in cash flows used in financing activities to cash flows provided by financing activities was due to no dividend payments to shareholders or share repurchases during the three months ended March 31, 2017 due to the pending transaction with Fairfax.

Investments

Our funds are primarily invested in liquid, high-grade fixed income securities. As of March 31, 20162017 and December 31, 2015, 90.7%2016, 92.2% and 90.1%, respectively, of our fixed income portfolio consisted of investment grade securities.

We have investments in “other invested assets”, comprisingcomprised of interests in hedge funds, private equity funds and other private securities, the carrying value of which was $940.3$966.6 million as of March 31, 2016.2017. Some of these funds have redemption notice requirements. For each of our funds, liquidity is allowed after certain defined periods based on the terms of each fund. See Note 4(b) “Investments — Other Invested Assets” to our unaudited condensed consolidated financial statements for additional details on our other invested assets.

We do not believe that inflation has had a material effect on our consolidated results of operations. The potential exists, after a catastrophe loss, for the development of inflationary pressures in a local economy. The effects of inflation are considered implicitly in pricing. Loss reserves are established to recognize likely loss settlements at the date payment is made. Those reserves inherently recognize the effects of inflation. The actual effects of inflation on our results cannot be accurately known, however, until claims are ultimately resolved.

Credit Facilities

In the normal course of our operations, we enter into agreements with financial institutions to obtain secured and unsecured credit facilities.

Allied World Assurance Company, Ltd currently has access to up to $1.05$1.1 billion in letters of credit under two letter of credit facilities, a $900 million uncommitted secured facility with Citibank Europe plc and a $150$200 million committed secured credit facility with a syndication of lenders (the “Amended Secured Credit Facility”). These credit facilities are primarily for the issuance of standby letters of credit to support obligations in connection with the insurance and reinsurance business.

The letters of credit issued under the credit facility with Citibank Europe plc are deemed to be automatically extended without amendment for twelve months from the expiry date, or any future expiration date unless at least 30 days prior to any expiration date Citibank Europe plc notifies us that they elect not to consider the letters of credit renewed for any such additional period.

A portionIn June 2016, we entered into a credit agreement (the “Credit Agreement”) that provides for a $200 million five-year senior unsecured revolving credit facility (the “Facility”) for the making of revolving loans and short-term swingline loans to us. The aggregate commitment of $200 million under the Amended Secured Credit Facility may alsobe increased by up to $150 million upon our request and upon the agreement of one or more Lenders or additional lenders. Borrowings in the form of swingline loans are subject to a sublimit of $25 million included within the $200 million aggregate commitment. Borrowings under the Credit Agreement may be used for revolving loansby us for general corporate and working capital purposes, up to a maximum of $150 million. We may request that existing lenderspurposes. Borrowings under the Amended Secured Credit Facility makeAgreement bear interest at a rate selected by us and equal to either the Base Rate or LIBOR plus a margin, other than swingline loans, which will only bear interest at the Base Rate plus a margin, as more fully set forth in the Credit Agreement. The Credit Agreement requires that all revolving loans be repaid in full

no later than the fifth anniversary of the Closing Date and that any swingline loans be repaid in full no later than the earlier of (i) ten business days after such swingline loan is made and (ii) the fifth anniversary of the Closing Date. The Company and Holdings have unconditionally guaranteed the obligations under the Facility.

We will pay customary arrangement and administration fees under the Credit Agreement. There is an additional commitmentsfee payable at an annual rate based upon the long-term senior unsecured debt ratings of Holdings and the Company in effect from time to time up to $150 million, subject to approval byon the lenders. average daily unutilized commitments of the Lenders.

The Amended Secured Credit FacilityAgreement contains representations, warranties and covenants customary for similar bank loan facilities, including certain covenants that, among other things, require usa covenant to maintain a certain leverage ratio and financial strength rating. The Amended Secured Credit Facility expires in June 2016. We expectof Consolidated Indebtedness to replace the Amended Secured Credit Facility with a new syndicated facility. We are in compliance with all covenants under the Amended Secured Credit FacilityTotal Capitalization as of March 31, 2016.the last day of each fiscal quarter or fiscal year of not greater than 0.35 to 1.0 and a covenant that the Consolidated Net Worth of the Company and its subsidiaries, as of the last day of any fiscal quarter or fiscal year, not fall below a minimum amount calculated based on Consolidated Net Worth, as adjusted for increases due to income or issuances of capital stock and decreases due to extraordinary dividend payments and stock repurchases. The Credit Agreement also has customary Events of Default, including (subject to certain materiality thresholds and grace periods): payment defaults; failure to comply with covenants; material inaccuracy of any representation or warranty; cross-defaults to other material debt or hedging obligations; unsatisfied judgments or pension obligations; bankruptcy, liquidation or insolvency proceedings; the issuance of any orders of conservation or supervision with respect to, or certain other matters relating to insurance licenses held by, any Material Insurance Subsidiary; and certain change in control events.

As of March 31, 2016,2017, we had a combined unused letters of credit capacity of $580.3$473.6 million from the Amended Secured Credit Facility and Citibank Europe plc. We believe that this remaining capacity is sufficient to meet our future letter of credit needs. During the three months ended March 31, 2016,2017, we did not utilize the revolving loan available under the Amended Secured Credit Facility.

In September 2014, Allied World Assurance Company, AG entered into a 20-year mortgage commitment with a Swiss bank for the purchase of three floors in an office building in Zug, Switzerland. See “Long-Term Debt” below for additional information regarding the 20-year mortgage commitment. In conjunction with the mortgage commitment, Allied World Assurance Company, AG entered into a three-year credit facility with a Swiss bank that provided us $5.2$5.1 million (CHF 5.0 million) for general corporate purposes; however, we used the proceeds from the credit facility to fund the purchase of three floors of the office building in Zug, Switzerland. The interest rate for the credit facility is 2.5%.

Pledged Assets

We use trust accounts primarily to meet security requirements for inter-company and certain reinsurance transactions. We also have cash and cash equivalents and investments on deposit with various state or government insurance departments or pledged in favor of ceding companies in order to comply with reinsurance contract provisions and relevant insurance regulations. In addition, our credit facilities are collateralized, at least to the extent of letters of credit outstanding at any given time.

Security arrangements with ceding insurers may subject our assets to security interests or require that a portion of our assets be pledged to, or otherwise held by, third parties. Both of our letter of credit facilities are fully collateralized by assets held in custodial accounts at the Bank of New York Mellon held for the benefit of the banks. Although the investment income derived from our assets while held in trust accrues to our benefit, the investment of these assets is governed by the terms of the letter of credit facilities or the investment regulations of the state or territory of domicile of the ceding insurer, which may be more restrictive than the investment regulations otherwise applicable to us. The restrictions may result in lower investment yields on these assets, which may adversely affect our profitability.

As of March 31, 20162017 and December 31, 2015, $2,703.42016, $2,719.8 million and $2,748.9$2,687.7 million, respectively, of cash and cash equivalents and investments were deposited, pledged or held in escrow accounts in favor of ceding companies and other counterparties or government authorities to comply with reinsurance contract provisions, insurance laws and other contract provisions.

In addition, as of March 31, 20162017 and December 31, 2015,2016, a further $631.8$575.3 million and $579.3$587.6 million, respectively, of cash and cash equivalents and investments were pledged as collateral for our credit facilities.

We do not currently anticipate that the restrictions on liquidity resulting from restrictions on the payment of dividends by our subsidiary companies or from assets committed in trust accounts or to collateralize the letter of credit facilities will have a

material impact on our ability to carry out our normal business activities, including interest and dividend payments, respectively, on our senior notes (described below) and common shares.

Financial Strength Ratings

Financial strength ratings represent the opinions of rating agencies on our capacity to meet our obligations. In the event of a significant downgrade in ratings, our ability to write business and to access the capital markets could be impacted. Our financial strength ratings as of March 31, 20162017 have not changed since December 31, 2015.2016. See Item 1. “Business” in our 20152016 Annual Report on Form 10-K.

warrants to purchase debt securities of Allied World Bermuda or units which may consist of any combination of the securities listed above. The registration statement is intended to provide us with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and our capital needs.

Share Repurchases

On May 1, 2014,April 19, 2016, our shareholders approved a share repurchase program in order for us to repurchase up to $500.0 million of our common shares. Under the terms of this share repurchase program, the first three million of common shares repurchased will remain in treasury and will be used by us to satisfy share delivery obligations under our equity-based compensation plans. Any additional common shares will be designated for cancellation at acquisition and will be canceled upon shareholder approval. We do not anticipate repurchasing any of our common shares pending the completion of the Fairfax transaction. As of March 31, 2016,2017, approximately $123.1$400.4 million remained under this share repurchase authorization.

During the three months ended March 31, 2016, our share repurchases were as follows:

Shares repurchased by the Company and not designated for cancellation are classified as “Treasury shares, at cost” on the consolidated balance sheets. The Company will issue shares out of treasury principally related to the Company’s employee benefit plans. Shares repurchased and designated for cancellation are constructively retired and recorded as a share cancellation.

Long-Term Debt

In July 2006, Allied World Bermuda issued $500.0 million aggregate principal amount of 7.50% senior notes due August 1, 2016, with interest payable in arrears August 1 and February 1 each year. Allied World Bermuda can redeem the senior notes prior to maturity, subject to payment of a “make-whole” premium; however, Allied World Bermuda currently has no intention of redeeming the notes prior to their stated maturity.

In November 2010, Allied World Bermuda issued $300.0 million aggregate principal amount of 5.50% senior notes due November 1, 2020, with interest payable in arrears May 15 and November 15 each year, commencing May 15, 2011.year. Allied World Bermuda can redeem the senior notes prior to maturity, subject to payment of a “make-whole” premium; however, Allied World Bermuda currently has no intention of redeeming the notes prior to their stated maturity.

In October 2015, Allied World Bermuda issued $500 million aggregate principal amount of 4.35% senior notes due October 29, 2025, with interest payable April 29th29 and October 29th29 each year, commencing April 29, 2016. We intend that theyear. The proceeds from these senior notes will bewere used to refinancerepay the senior notes due to mature inthat matured on August 1, 2016. Allied World Bermuda can redeem the senior notes prior to maturity, subject to payment of a “make-whole” premium; however, Allied World Bermuda currently has no intention of redeeming the notes prior to their stated maturity.

The payment of principal of, and the interest on, the senior notes issued in 2006, 2010 and 2015 have been unconditionally and irrevocably guaranteed for the payment of the principal and interest by Holdings.

In September 2014, Allied World Assurance Company, AG entered into a 20-year mortgage commitment with a Swiss bank for the the purchase of three floors in an office building in Zug, Switzerland. The total proceeds received in 2014 under the mortgage was $14.1 million (CHF 14.0 million) with a fixed annual interest rate of 3.2% payable quarterly, and an

additional $4.1$4.0 million (CHF 4.0 million) of proceeds from the mortgage was received in April 2015. The mortgage payments will be $0.3 million (CHF 0.3 million) per year, plus accrued interest, for the first 19 years, with the remaining balance payable at the end of the mortgage.

Off-Balance Sheet Arrangements

As of March 31, 2016,2017, we did not have any off-balance sheet arrangements.
Item 3.Quantitative and Qualitative Disclosures About Market Risk.
We believe that we are principally exposed to three types of market risk: interest rate risk, credit risk and currency risk.
The fixed income securities in our investment portfolio are subject to interest rate risk and credit risk. Any changes in interest rates and credit spreads have a direct effect on the fair values of fixed income securities. As interest rates rise, the fair values fall, and vice versa. As credit spreads widen, the fair values fall, and vice versa.
In the table below, changes in fair values as a result of changes in interest rates are determined by calculating hypothetical March 31, 20162017 ending prices based on yields adjusted to reflect the hypothetical changes in interest rates, comparing such hypothetical ending prices to actual ending prices, and multiplying the difference by the principal amount of the security. The sensitivity analysis is based on estimates. The estimated changes of our fixed maturity investments and cash and cash equivalents are presented below and actual changes for interest rate shifts could differ significantly.

As of March 31, 2016,2017, we held $7.6$6.5 billion of fixed income securities. Of those assets, approximately 90.7%92.2% were rated investment grade (Baa3/BBB- or higher) with the remaining 9.3%7.8% rated in the below investment grade category. TheAs of March 31, 2017, the average credit quality of the fixed maturity portfolios was rated AA- by Standard & Poor’s.
Our agency pass-through mortgage-backed securities are exposed to prepayment risk, which occurs when holders of individual mortgages increase the frequency with which they prepay the outstanding principal before the maturity date to refinance at a lower interest rate cost.rate. Given the proportion that these securities comprise of the overall portfolio, and the current interest rate environment and condition of the credit market, prepayment risk is not considered significant at this time.
Our non-agency commercial mortgage-backed securities are subject to the risk of non-payment due to increased levels of delinquencies, defaults and losses on commercial loans that cumulatively create shortfalls beyond the level of subordination in our specific securities.
As of March 31, 2016,2017, we held investments in “other invested assets” with a carrying value of $940.3$966.6 million. Included in other invested assets are private equity funds, hedge funds and other private securities. Investments in these types of assets involve certain risks related to, among other things, the illiquid nature of the fund shares, the limited operating history of these investments, as well as risks associated with the strategies employed by the managers of these investments. The funds’ objectives are generally to seek attractive long-term returns with lower volatility by investing in a range of diversified investment strategies. As our reserves and capital continue to build, we may consider additional investments in these or other alternative investments.

The U.S. dollar is our reporting currency and the functional currency of all of our operating subsidiaries, except for our Hong Kong and Singapore operations. We enter into insurance and reinsurance contracts where the premiums receivable and losses payable are denominated in currencies other than the U.S. dollar. In addition, we maintain a portion of our investments and liabilities in currencies other than the U.S. dollar, primarily the Euro, British pound sterling, Swiss Francfranc and Canadian dollar. Receivables in non-U.S. currencies are generally converted into U.S. dollars at the time of receipt. When we incur a liability in a non-U.S. currency, we carry such liability on our books in the original currency. These liabilities are converted from the non-U.S. currency to U.S. dollars at the time of payment. As a result, we have an exposure to foreign currency risk resulting from fluctuations in exchange rates. We utilize a hedging strategy to minimize the potential loss of value caused by currency fluctuations by using foreign currency forward contract derivatives that expire in 90 days from purchase.
As of March 31, 20162017 and December 31, 2015,2016, approximately 8.7%7.3% and 10.0%6.8%, respectively, of our total investments and cash and cash equivalents were denominated in currencies other than the U.S. dollar. Of our business written during the three months ended March 31, 2017 and 2016, approximately 19% and 2015, approximately 20% and 15%, respectively, was written in currencies other than the U.S. dollar.
Item 4.Controls and Procedures.

In connection with the preparation of this quarterly report, our management has performed an evaluation, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of March 31, 2016.2017. Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosures. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2016,2017, our Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms and accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide an absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.

No changes were made in our internal controls over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f), during the quarter ended March 31, 20162017 that hashave materially affected, or isare reasonably likely to materially affect, our internal control over financial reporting.
